Abstract: Objective To observe the clinical effect of digital subtraction angiography (DSA) combined with doublechamber Fogarty catheter in venous crisis after replantation of severed extremities. Methods A total of 12 cases with venous crisis after replantation of severed extremities treated by DSA combined with double-chamber Fogarty catheter from June 2011 to January 2016 were included in this study. Results Eleven cases survived after operation. Healing status of surgical incisions was stage Ⅰ for all patients. Of which osteofascial compartment syndrome was found in 1 case, and it was cured by surgical incision treatment; liver damage was found in another case, and acute liver damage was treated by comprehensive treatment of internal medicine. The postoperative venous thrombosis was found again in one case. The patient underwent exploratory surgery, and venous thrombosis was found again, limb partial necrosis was found, amputation was perform, and the incision was healed in Ⅰ stage. Complications including vascular rupture, air embolism, infection and sepsis were not found in all patients. Thrombosis was presented in the vein, the length of 0.6-4.2 cm. A total of 11 patients were treated with Fogarty catheters and followed up for 11 months (7 months to 29 months). The limb shape of the patient was satisfactory, blood supply of limb was improved, and capillary filling time was 1.5-3.3 s, swelling degree was improved, skin temperature was normal or lower than the limb 0.6-1.5 ℃, the skin color was normal, the activity improved, the feeling of recovery S0- S4 levels, the average in the S3 + level, two- point discrimination was 3- 8 mm with an average of 4.5 mm. According to the evaluation criteria of the replantation function of the limb replantation of the Chinese Medical Association, 5 cases were excellent, 4 cases were good and 2 cases were poor. Conclusion The application of DSA combined with double- chamber Fogarty balloon catheter for the treatment of venous crisis shows precise localization of thrombosis, increased targeting venous branch in blood vessels, minimally invasion, quick, and satisfactory clinical results.
